Small changes inspired by Wednesday's discussions:
- Mac only: Gmsh now publishes its "file types"... That means that
geo/msh/pos files now have nice icons, and that you can double-click
on a geo/msh/pos file in the Finder to open it :-)
- removed support for fltk 1.0 (wasn't compiling anymore anyway)
- doubled the timout in GmshServer (2->4s): this seems to help on
Windows (thanks to jkools@veeco.com)
- added warnings in the docs about the Attractor feature
- increased WB by 1 pixel in the GUI
- replaced more Msg(FATAL) with Msg(ERROR) where it makes sense
